Document Type and Number:

Japanese Patent JP4557566

Kind Code:

B2

Abstract:

To provide a treatment method for a contaminated object to be treated capable of treating contaminated water and mud, or the like, containing hazardous substances such as DXNS (dioxins) and heavy metals by relatively simple treatment facilities and processes at low costs, and obtaining filtered water under the emission regulations by surely capturing the hazardous substances to suppress the elution by enclosing the water in a dehydrated cake.

The treatment method is for treating the contaminated water containing DXNS, or the like, generated in cleaning work at demolition work, or the like, in a waste incineration facility, the contaminated mud containing DXNS, or the like, of dredged spoil, or the like, of dredged bottom sediment of harbors, and the heavy metals contaminated soil (B mud slurry). Stone dust for capturing DXNS, or the like, and A mud slurry ASwherein an adsorbent is added to mud materials such as bentonite are placed in a filtration chamber such as a filter press 8. B mud slurry BScomprising the contaminated water is placed in the A mud slurry AS. The B mud slurry is dehydrated using the A mud layer as a filter and a desorption layer, and is subjected to solid/liquid separation to obtain the dehydrated cake C and filtrated water W. The DXNS and heavy metals, or the like, are enclosed inside the dehydrated cake (A mud and B mud) by capturing, desorbing, insolubilizing, or the like.
